New law for resolution allows unprecedented sharpness in fluorescence microscopy
...ics, resolutions at the nano-level are possible in fluorescing
samples. In an additional publication , the researchers show that STED microscopy allows one to image lithographic structures (which had been previously dyed with a fluorescent dye) of width as small as 40-80 nm, a size previously reserved for ele...
Tissue regeneration operates differently than expected
...labelled with the green dye. In contrast, no green fluorescing
muscle cells became evident when stem and muscle cells were spatially separated by a membrane between both cell types. The researchers conclude that this experiments proofs that cell fusion of mesenchymal stem cells and muscle cell but not their tran...
Encoded metallic nanowires reveal bioweapons
...the reflection pattern allows the "barcode" of the fluorescing
nanowires to be read. If only wires with stripe pattern 1 fluoresce, for example, then the sample contains anthrax spores. One particular advantage of nanowires over other antibody supports is that the tests do not take place at a surface but instead...
Catching cancer's spread by watching hemoglobin
...free," meaning it does not require the addition of fluorescing
molecules but rather relies on the inherent light-absorbing properties of hemoglobin. While the technique has been demonstrated in vitro (by excising tissue samples and imaging the vessels on a glass dish), imaging in the living body is possible eith...
